Correct me if I'm wrong but as I understand it the following is the bone transformation procedure:
R = current anim key rotation matrix T = current anim key translation matrix R1 = next anim key rotation matrix T1 = next anim key translation matrix G = transform matrix G1 = parent transform matrix I = inverse root matrix O = bone offset matrix F = final transform for bone So: G = interp(R, R1) * interp(T, T1); F = I * G * G1 * O;
That is alot of matrix multiplications each frame. Is there anything that can be done to simplify and speed up the process?
Are there any matrices that can be "baked" / pre-transformed without causing artifacts during animation (interpolation) ?
